CAPM Practice: Determine how to document project controls of predictive, plan-based projects

A ±10% threshold means the project manager initiates a formal review when performance is more than 10% off plan in either direction. SPI = 0.87 represents a 13% shortfall (below the -10% threshold), triggering a formal review. SPI values of 0.95, 1.05, and 1.08 are all within the ±10% window and would not trigger a formal review under this policy.

**Why not A:** SPI = 1.05 represents 5% above plan, which is within the plus or minus 10% threshold. This performance level does not trigger a formal review because it falls within the acceptable range of normal variation.

**Why not B:** SPI = 1.08 represents 8% above plan, which is still within the plus or minus 10% threshold. While favorable, this level of positive variance does not exceed the defined threshold that would trigger a formal review.

**Why not C:** SPI = 0.95 represents 5% below plan, which is within the minus 10% threshold. While unfavorable, this level of negative variance is within the acceptable range and does not trigger the formal review mechanism.
